Camera optical lens

Abstract

A camera optical lens includes from object side to image side: first lens, second lens, third lens, fourth lens, fifth lens, sixth lens and seventh lens. Central curvature radius of object-side surface of fourth lens is R7, central curvature radius of image-side surface of fourth lens is R8, a field of view of camera optical lens is FOV, f-number of camera optical lens is FNO, total optical length from object-side surface of first lens to image plane of camera optical lens along optic axis is TTL, on-axis thickness of second lens is d3, focal length of sixth lens is f6, focal length of seventh lens is f7, and following relational expressions are satisfied: 1.00≤R7/R8≤3.00; 80.00≤FOV/FNO≤120.00; 10.00≤TTL/d3≤20.00; −4.00≤f6/f7≤−1.00. The camera optical lens has good optical performance such as large aperture and wide-angle.
